The shader in 2.8 an 2.81 is still shown even if it is 100%, whilst in 2.8 beta it works fine to show the current texture that I am painting on. As you can see here. (https://i.stack.imgur.com/DbiyD.png). I tried to report this as a bug but a guy came back to me that slider is for masking opacity now. I have no idea why it works for the masking opacity when it is was clearly for the texture opacity before. Seems like a silly change despite the label not being different. Regardless is it possible to change the visual of flat versus shaded with a slider?
